Mode of heating wheel-tikes



ALVA GREGORY, OF PIKE, NEW YORK.

MODE OF HEATING WHEEL-TIRES.

S-pecifn'saton of Letters Patent No. 5,259, dated August 28, 1847.

To all whom t may concern:

Be it known that I, ALvA GREGORY, of Pike, in the county of Wyoming and State of New York, have invented a new and useful Circular Tire-Furnace for Heating Carriage Tires preparatory to Setting the Same; and I do hereby declare that the following is a full, clear, and exact description of the construction and operat-ion of the said furnace, reference being had to the ac-. companying drawings, making part of this specification.

The main drawing is intended torepresent a perspective view of said furnace; which is constructed of two circular sides of cast or sheet iron plates of different circumferences, and standing on a circular bottom, and thus forming a circular space between the two sides, suiiiciently large to admit the recept-ion of tire of dierent sizes, together with fuel or coal necessary to heat the same; said furnace is covered over with a circular cast or sheet iron top, in which is a number of holes to admit a draft of air, which may be closed by slidesl at pleasure to conne the heat in the furnace.

A represents a section of the bottom of the furnace with small hearths 1 l, l, l, projecting on both sides `before the draft holes 2, 2, 2, 2 which are formed when the sides are properly placed on the bottom.

B represents a section of the outer circular side with notches in the under edge, for draft'holes when placed on the bottom and with flanges at 3, 3 on the inside for the grate to rest on. C a segment of the inner circular side with notches and flanges the same as the outside. D clasps to be placed over the joints of the side segments on the upper edge thereof to keep them inv place, when not made whole.

E represents a segment of the grate with an elevated piece as u, across one vend for the tire to -lie on; and openings in the grate -to admit a draft of air.

F represents a section of the coyer or top to the furnace, with openings which may be closed by slides when the fuel becomes ignited, so as to confine the heat when necessary.

Gr is a piece of pipe put into one of the outside section near the top; other pipe may be attached if necessary. l

H is a tew iron in one of the side pieces to receive a bellows nose when necessaryto produce a more rapid combustion of coal or A fuel.

I, is one of the legs, one end dove tailed to correspondvto projections on the underside ends of the bot-tom piecey at J and when slid on keeps them in place. j v

The advantages to be derived from the use of this `furnace are that by confining the heat a great saving of co-al or other fuel used in heating Athe tire is effected, and the tire is heated in less time and more uniform than4 by the old method. Another advantage is that sea or charcoal may be used, which is a very important item where wood is scarce.

This furnace may be used iny inclosed wooden buildings with as much safety as a common stove and when constructed in sections it may be taken down and laid aside when not wanted for present use.

What I claim as original and desire to secure by Letters Patent, isv The invention of a circular furnace' for heating carriage tire, by conning the heat particular materials or dimensions in con-V 'structing the furnace; while I obtain the same and by substantially the same means.
